SASI-I-LOCK.

Specification of Letters Patent.

Patented June 22, 1915.

Application filed July 21, 1914. Serial No. 852,239.

To all whom it may concern:

Be it known that I, GEORGE E. HALL, a citizen of the United States, residing at Fremont, in the county of Newaygo and State of Michigan, have invented certain new and useful Improvements in Sash-Locks, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to certain new and useful improvements in sash locks and has for its objects to provide a lock which may be readily secured in place without penetrating or mutilating the inner edge of the sash and providing convenient and eifectlve means for operating the look.

It has also for its object to so form and arrange the means by which the locking bolt is operated that it shall also subserve the purpose of a properly disposed and ef fective sash lift.

With these generic objects in View, my invention consists in the construction and arrangement of the parts as will be hereinafter more fully set forth.

In order that those skilled in the art to which my invention appertains may know how to make and apply my improved sash lock and lift and to fully appreciate all of its advantages I will proceed to describe the same referring by numerals to the accompanying drawing in which Figure l is an elevation showing a window frame and lower sash with my im proved lock applied to the right hand side of the sash; Fig. 2 is a similar View showing the lock applied to the left hand side of the sash; Fig. 3 is a cross section on the line aa of Fig. l with bolt extended; Fig. 4: is a similar View with bolt withdrawn and spring compressed; and Fig. 5 is an elevation looking toward the inside edge of the sash.

Similar numerals indicate like parts in the several figures of the drawing.

1 represents an ordinary window frame which is provided with any number of suitable bolt recesses according to the position in which it may be desired to lock the sash. 2 is a cylindrical recess or pocket bored into the sash 3 from its outer edge and into which is placed a tubular bolt guide 4, constituting also a reinforce for a reciprocatory bolt 5, which is operated by means of a short screw 6, movable through a horizontal slot 7, in a plate 8, which plate is secured in place by a screw 9, at its lower end and by another screw 10, at its upper end, which former constitues a pivot upon which the bolt operatng lever 11 vibrates. This operating lever is connected with the bolt by means of the screw 6, which passes through one of the holes 12 in the plate 8, accordingly as the lock is used on one or the other sides of the sash as shown in Figs. 1 and 2.

Attention is called to the fact that in the drawing I have shown the lever 11 as turned outwardly at its upper extremity to constitute a sash lift 13, but it will be understood that I do not wish to be confined to any exact form of the lever so long as it serves the purpose of a lift.

I will now describe the pecularities of construction of the locking bolt 5, especial reference being had to Figs. 3 and 4.

As shown, the bolt is hollow, or tubular in cross section and is closed at each end by tubular bushings 14 and 15, each of which is provided with a central orifice 16 for the reception of a spring compressing rod 17, which is provided about central of its length with a suitable spring bearing or seat 18. Surrounding the rod 17 is arranged a coil spring 19, one end of which is seated against the bushing 14 in the forward end of the hollow bolt 5, and the other against the seat 18, on the spring compressing rod 17. In locating this spring and its compressing rod they are first placed within the bolt from the front end thereof and the bushing 15 is then passed over the compressing rod and connected in the front end of the bolt, so that as will be seen, the spring is thus confined between the bushing 141 and seat 18 and operates to hold the bolt in its extended or looking position as shown in Fig. 3, and in Fig. 4-, the bolt is shown as retracted and the spring contracted or under compression ready to shoot the bolt when the operating lever is released. As shown the bolt is preferably made of the same diameter throughout its entire length, but may be varied in this particular without departing from the genus of my invention.

From the construction shown and described it will be seen that when the several parts of the bolt have been duly assembled and placed within its tubular bushing or bearing in the outside edge of the sash, and the operating screw 6 is passed through one of the holes or orifices in the lever 11', and the horizontal slot 7 of the face plate and screwed into the bolt 5, the latter is thus held in its proper relation with the sash, and as previously stated the bolt and its operative members may be placed on either side of the sash and accordingly the screw is passed through one or the other of the holes or orifices 12, in the lever 11 and in either case as the'lever is connected with the bolt mechanism above the axis of motion of the lever, and in retracting the bolt the lever is moved away from the window frame and beyond the inner edge of the sash where the projection at the upper end of the lever can be conveniently used to both lift or force downward the sash.

The bolt and its tubular bushings may be made of malleable cast iron or of any other suitable material and the face plate 8, and vibratory lever 11, are preferably made from sheet metal. The bushings at each end of the bolt may be secured therein in any suitable manner, but I have found from experience that when adapted for a c ose fit, and driven in, the union between them and the hollow bolt will be su'liicient to hold them against any pressure which may be exerted by the spring. hen pressed or driven in, care should be taken in so far as the bushing 15 is concerned to bring the screw hole therein into alinement with the screw hole in the bolt into which the screw 6 is threaded.

Having described the construction, operation and advantages of my improvement what I claim as new and desire to secure by Letters Patent is:

1. In a sash lock and lifter, an operating lever adapted to act as a hand hold and normally resting against the face of the sash, said lever being pivoted at its lower end, a bolt operatively connected with the lever above the pivotal axis of the lever, whereby as the lever is operated to fully retract the bolt the upper end of the lever is moved outwardly to its fullest extent beyond the inner edge of the sash, and therefore away from the jamb and in position to be conveniently employed for raising and lowering the sash.

2. In a sash lock and window lifter, a reciprocatable bolt, an operating lever having a fixed pivot and operatively connected with the bolt to entirely retract the bolt upon an outward movement of the lever to its extreme position, and means for limiting the outward movement of the lever to prevent its upper end at any time being disposed below the pivotal axis of the lever.

3. In a sash lock such as describedand embodying a reciprocatory bolt within a mortise in the sash, and a lever connected with the bolt by a screw, screw holes or passages on opposite sides of its vertical center whereby the lock may be employed on the right or left sides of the sash, accordingly as the screw connecting the lever to the bolt is placed through one or the other of the screw holes or passages as hereinbefore set forth.

In testimony whereof I hereunto affix my signature in the presence of two witnesses. GEORGE It. HALL.
